LASIK surgery, short for Laser-Assisted In Situ Keratomileusis, is a popular refractive eye surgery that uses an excimer laser to reshape the cornea. This procedure aims to correct common vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, reducing or eliminating the need for glasses or contact lenses.
LASIK eye surgery is a minimally invasive procedure that involves creating a thin flap on the cornea's surface. This flap allows access to the underlying tissue where the laser reshapes the cornea to correct vision issues. The entire process typically takes around 15 minutes per eye and can significantly improve visual acuity.
The LASIK procedure begins with numbing drops applied to the eyes, followed by the creation of a thin flap in the cornea using either a microkeratome or a femtosecond laser. Once the flap is lifted, an excimer laser shapes the underlying tissue based on preoperative measurements taken during your consultation. The flap is then repositioned, and the eye heals naturally without stitches.
LASIK is suitable for individuals aged 18 years or older with stable vision who are not pregnant and do not suffer from certain eye conditions like severe dry eyes, keratoconus, or corneal scars. A thorough evaluation by an ophthalmologist will determine if you are a good candidate.
While LASIK is one of the most popular refractive surgeries, alternatives like PRK (Photorefractive Keratectomy) and ICL (Implantable Collamer Lens) also exist. Each has its own set of advantages and disadvantages depending on your specific needs and eye health.
Before undergoing LASIK, you will need to schedule a comprehensive pre-operative evaluation with an ophthalmologist. This includes measuring corneal thickness, mapping the surface curvature of the eye (topography), and assessing overall ocular health. Follow all pre-surgery instructions provided by your surgeon.
Most patients experience little to no discomfort after surgery but may notice some dryness or irritation initially. Use prescribed medications as directed, avoid rubbing your eyes, and protect them from dust and debris with protective eyewear if necessary.
The cost of LASIK surgery varies depending on several factors including geographic location, surgeon experience, and specific treatment needs. In the United States, prices range from $1500 to over $4000 per eye. Many clinics offer financing options or discounts for both eyes.
LASIK surgery offers a transformative solution for individuals seeking freedom from glasses and contacts. By understanding what LASIK entails, its benefits, risks, and costs, you can make an informed decision about whether this procedure is right for you. Consult with an experienced ophthalmologist to explore your options further.
